JOHN VEIOHHART, OF SAN FRANCISCO, CALIFORNIA.

FEED-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No, 298,527, dated May 13, 1884.

Applicaiion filed January 24, 1884. (No model.)

T 0 LZZ whom, t may concern.-

Be it known that I, JOHN WEICHHART, of the city and county of San Francisco,and State of California, have invented certain new and useful Improvements in Feed-Cutting Hachines and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, forming a part of this specification.

My invention relates to an improved gearing mechanism for feed-cutting machines, and more particularly to certain improvements on the feed-cutting machine for which Letters Patent were granted to me on the 16th day of March. 188i), and the 4th day of October, A. D. 1881, respectively.

The invention consists in the construction, arrangement,and combination of parts, as hereinafter more fully described and claimed.

Figure l is a perspective view of my improved feed-cutting machine. Fig. 2 is aside View of the same, the usual housings or shields which cover and protect the gearing being removed. Fig. 3 is a side elevation showing the gearing upon the further or left-hand side Fig. 4 is a vertical cross-section showing the feed-rollers, the depressionplate, and the cutter-bar.

Similar letters of reference are used to indicate like parts throughout the several ures.

rIhe feed-box A and cutting-wheel B are constructed much in the usual manner, and the shaft B of the cutting-wheel is extended along the side of the feed-box, and journaled in suitable bearings, B2 and B3, attached to the frame-work of the machine. The shaft Bhas a bevel-pinion, C, upon its rear end, which engages with a bevel-wheel, D, on the drivingcrank, by means of which it is driven. The forward end of the shaft B projects in advance of the front end of the cutting or feed box, and has the cutting fly-wheel I3 secured to it, so as to cut across the end of the box, as described in my former patents. About midway of the length of the shaft B, I place the worm-gear F, which meshes with a cog-wheel, G, placed directly beneath it, and upon a shaft, G', which extends across the machine beneath the iioor of the feed-box, and is provided upon the opposite end with a removable gear-wheel, G2, which in turn meshes with the removable gear-wheel H upon the spindle H of the lower feed-roller, H2. The object in making these two last-named gear-wheels re- 5 5 movable is to permit of the substitution of -wheels of different diameters, in order to regulate the rate of feed or speed with which the straw is fed to the cutting-wheel. Upon the other end or spindle, H, of the said lower feed- 6o roller I secure the pinion H4, which drives the gear-wheel I of the upper feed-roller, I', through the medium ot' the intermediate pinions, L and M, journaled upon arbors projecting from the side of the machine. rI he spin- 65 dles or journals N N of the upper feed-roller project through slots O, formed in the side of the feed-box, and are journaled in the curved arms I? P, which extend downward on each side of the box, and have their lower ends con- 7o nected by a cross-bar, a, which passes across underneath the box. A pin, b, projects downward from the middle of this cross-bar and passes through a hole in the timber c underneath the cross-bar, and serves as a guide for the arms and cross-bar. Ailat spring, d, passes along under the box,having its spring end resting upon the cross-bar a, while its opposite end passes below a' cross-beam, e, near the rear end of the feed -box. A set screw, f, is passed through a hole in the outer end of the spring and into the under side of the box, as shown by dotted lines in Fig. 2, and serves, by turning it in or out, to increase or diminish the pressure of the opposite end ofthe spring upon the S5 cross-bar. The slots O O are curved and form segments of a circle of which the spindle of the upper idler or intermediate pinion, M, is the center; and by this arrangement it will be seen that as the said upper feed-roller is raised or 90 depressed its path of travel will be concentric with its driving-pinion, and the teeth of the gears will be at all times in proper contact, and the action of the feed-roller will be regular and positive. The arms l? pass between the sides of the feed-box and the inner faces of the gearwheels, and are bent downward and forked to receive the lugs Q of the depression plate or bar Q', which pass through slots Q2 in the sides of the feed-box, and are held in `place by pins or bolts, as shown in Fig. 3. This plate or bar extends across the outlet of the feed-box from IOO side to side almost directly over the cutter-bar It, and its. ofiice is to hold down the straw upon the bar after it issues from thefeed-rollers',and its distance from the cutter-bar varies with the vertical movement of the upper feed-roller. By this arrangement of removable gearing I am enabled to vary the speed of the'i'eedrollers Without changing the speed of cuttingwheel shaft, and Without the employment of expensive concentric gears, sliding pinions, or clutches, and provide a machine adapted to cut feed of different lengths, of cheap and simple construction, and not liable to get out of order.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

l. In a feed-cutting machine, the combination of the cuttershai`t B', having Wormgear F, the shaft G', having gears G G2, the feedrollers I-I2 I', roller-gears II H1 I, and intermediate gears or pinions, L M, substantially as shown and described.

2. In a feed-cutting machine, the combination of the frame A, having slots O Q2, the feed-rollers H2 I' and connected gearing, the arms I?, depression-plate Q', cross-bars a c, pin b, spring d, and set-screw j', substantially as described.

3. In a feed-cutting machine, the combination of the cutter-bar R, depression-plate Q', having lugs Q Q, the curved arms I? I), crossbar a., spring d, ieedrollers H2 I', and actuating mechanism, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
